National Australia Bank (ASX: NAB) Reports $6.14 Billion Profit as Bad Debt Charges Surge 86%

National Australia Bank Limited (ASX: NAB) has reported $6.14 billion in annual statutory profit, but an 85.7% surge in credit impairment charges has exposed growing pressure beneath its expanding lending business.

Revenue increased 5.8% and underlying operating performance improved, yet adjusted cash earnings remained flat. The critical question is whether Australia's largest business lender can maintain profitability as economic conditions become more challenging.

Key Numbers

• $6.14 billion: FY26 statutory net profit, down 9.1% from FY25.
• $7.09 billion: Cash earnings excluding large notable items, broadly unchanged year-on-year.
• $1.55 billion: Credit impairment charges, up 85.7% from $833 million.
• 9.8%: Growth in Australian business lending balances during FY26.
• 85 cents: Fully franked final dividend per share, bringing annual dividends to $1.70.

The Latest Development: Stronger Revenue Meets Rising Credit Costs

NAB's full-year results, released on 5 November 2026, reveal stronger operating income alongside deteriorating credit conditions.

Underlying profit excluding large notable items increased 6.9%, supported by lending growth, improved margins and cost discipline.

Net interest margin increased six basis points to 1.80%, reflecting stronger deposit returns and modest funding cost benefits.

However, credit impairment charges increased from $833 million to $1.55 billion, including $403 million in additional forward-looking provisions.

These provisions reflect expectations of more challenging economic conditions rather than losses already realised.

Reported cash earnings declined 13.4% to $6.14 billion, including a $949 million after-tax impact from changes to software capitalisation accounting.

Excluding this significant item, annual cash earnings remained essentially flat.

What Stands Out to Us

NAB's business banking franchise continues demonstrating its competitive strength.

Business and Private Banking delivered $3.69 billion in cash earnings, representing 10.7% annual growth, supported by stronger lending volumes, improved margins and higher fee income.

However, Corporate and Institutional Banking earnings declined 6.1%, partly reflecting increased credit impairment charges.

This highlights an important vulnerability: expanding lending balances can strengthen revenue while simultaneously increasing exposure to borrowers experiencing financial difficulties.

NAB's balance sheet remains resilient, with a Common Equity Tier 1 capital ratio of 11.87% at 30 September 2026.

Management expects this ratio to reach approximately 12.07% following the anticipated impact of its discounted final dividend reinvestment plan.

For valuation, earnings quality remains central. NAB reported an 11.4% cash return on equity excluding large notable items, making sustained profitability and capital efficiency important measures of whether its market valuation is justified.

What the Company Is Doing Now

NAB is accelerating efforts to simplify operations, modernise technology and strengthen customer relationships.

The bank delivered $463 million in productivity benefits during FY26 while maintaining investment expenditure of approximately $1.8 billion.

It is also progressing plans to eliminate up to 2,500 internal positions during FY27, with an anticipated $300 million pre-tax restructuring charge.

Management expects underlying cost growth below 3% in FY27, excluding specified restructuring and software accounting impacts.

Alongside these changes, NAB continues prioritising business lending, deposits and direct mortgage distribution.

Australian home lending drawdowns through proprietary channels increased to 50% during FY26, compared with 41% in FY25.

Insight: Can NAB Protect Profitability as Credit Risks Increase?

We think NAB's core business remains fundamentally strong, supported by its established business banking franchise, improving margins and substantial capital buffers. However, the 85.7% increase in credit impairment charges is more consequential than headline revenue growth suggests. Stronger lending volumes offer limited benefit if additional credit losses absorb incremental earnings. The restructuring could improve efficiency, but its financial contribution remains unproven. Our assessment is cautiously constructive on the underlying franchise, although sustained earnings improvement will require credit conditions to stabilise alongside measurable cost savings.

What Happens Next?

NAB's next challenge is translating stronger operating performance into improved cash earnings.

Management forecasts Australian economic growth slowing to 1.0% during calendar 2027, potentially increasing pressure on households and businesses.

The most important indicators will be credit impairment charges, net interest margins and progress towards the FY27 underlying cost growth target.

Evidence of stabilising credit quality, combined with continued business lending growth, would strengthen NAB's earnings outlook.

For shareholders, the central issue is no longer whether NAB can expand its lending portfolio. It is whether that growth can generate sustainable profitability despite rising credit risks.
